Two glycoside hydrolase family 1 proteins mediate glycosylated modification at the 5-position of anthocyanin in grape hyacinth.

Glycosylation modification of anthocyanins is important as a preceding step to acylation modification. Cyanidin-3-O-(p-coumaroyl)glucoside-5-O-malonylglucoside (Cy3pCG5MaG) is one of the major anthocyanin substances in blue-flowered grape hyacinth, but its 5-position glycosylation is unknown. Here, we identified two glycoside hydrolase family 1 genes, MaAGGT1 and MaAGGT5, which use acyl-glucose as a donor and are involved in the glycosylation modification of anthocyanins in grape hyacinth.

Molecular Mechanism of ARF5-AHL15-Mediated Auxin-Induced Embryogenic Cell Formation in Apples.

The somatic embryo (SE) has bipolar characteristics, which is an ideal material for large-scale microproduction of woody plants represented by apples, and the somatic embryo is also an excellent receptor for genetic transformation. The formation of embryogenic cells is a prerequisite for somatic embryogenesis to occur. The embryogenic cells of apples cannot be obtained without induction of exogenous auxin, but how the auxin pathway regulates this process remains unknown.

Glycine Decarboxylase (GLDC) Plays a Crucial Role in Regulating Energy Metabolism, Invasion, Metastasis and Immune Escape for Prostate Cancer.

Glycine decarboxylase (GLDC) is one of the core enzymes for glycine metabolism and its biological roles in prostate cancer (PCa) are unclear. First, we found that GLDC plays a central role in glycolysis in 540 TCGA PCa patients. Subsequently, a metabolomic microarray showed that GLDC enhanced aerobic glycolysis in PCa cells, and GLDC and its enzyme activity enhanced glucose uptake, lactate production and lactate dehydrogenase (LDH) activity in PCa cells.

Anthocyanins from spp. inhibit the activity of by downregulating the expression of , , and .

plants are frequently devastated by the apple rust caused by Miyabe. When rust occurs, most spp. and cultivars produce yellow spots, which are more severe, whereas a few cultivars accumulate anthocyanins around rust spots, forming red spots that inhibit the expansion of the affected area and might confer rust resistance.

Current therapy and drug resistance in metastatic castration-resistant prostate cancer.

Castration-resistant prostate cancer (CRPC), especially metastatic castration-resistant prostate cancer (mCRPC) is one of the most prevalent malignancies and main cause of cancer-related death among men in the world. In addition, it is very difficult for clinical treatment because of the natural or acquired drug resistance of CRPC. Mechanisms of drug resistance are extremely complicated and how to overcome it remains an urgent clinical problem to be solved.

Overexpression of SPHK1 associated with targeted therapy resistance in predicting poor prognosis in renal cell carcinoma.

Background: Sphingosine kinase 1 (SPHK1) is a key enzyme that catalyzes the phosphorylation of sphingosine. Recent studies reported SPHK1 to be associated with renal cell carcinoma (RCC) progression by inducing targeted therapy resistance. However, the expression and the clinical significance of SPHK1 on RCC in those having received targeted therapy have not been elucidated.

Driving effects of land use and landscape pattern on different spontaneous plant life forms along urban river corridors in a fast-growing city.

River corridors are critical in connecting fragmented greenspace and providing habitats for plants and animals. There is a paucity of information on the detailed influence of land use and landscape patterns on the richness and diversity of distinct life forms of urban spontaneous vegetation. This study aimed to identify the variables that dramatically affect spontaneous plants and then disentangle how to manage such a variety of land types to maximize the biodiversity-supporting function of urban river corridors.

Synthesis, Thermal and Mechanical Properties of Fully Biobased Poly (hexamethylene succinate--2,5-furandicarboxylate) Copolyesters.

Poly (hexamethylene succinate) (PHS) is a biobased and biodegradable polyester. In this research, two fully biobased high-molecular-weight poly (hexamethylene succinate--2,5-furandicarboxylate) (PHSF) copolyesters with low hexamethylene furandicarboxylate (HF) unit contents (about 5 and 10 mol%) were successfully synthesized through a two-step transesterification/esterification and polycondensation method. The basic thermal behavior, crystal structure, isothermal crystallization kinetics, melting behavior, thermal stability, and tensile mechanical property of PHSF copolyesters were studied in detail and compared with those of PHS.

Plasma cell subtypes analyzed using artificial intelligence algorithm for predicting biochemical recurrence, immune escape potential, and immunotherapy response of prostate cancer.

Background: Plasma cells as an important component of immune microenvironment plays a crucial role in immune escape and are closely related to immune therapy response.

In this study, we intend to investigate the value of a new plasma cell molecular subtype for predicting the biochemical recurrence, immune escape and immunotherapy response in prostate cancer.

Exosomes derived from BMSCs ameliorate cyclophosphamide-induced testosterone deficiency by enhancing the autophagy of Leydig cells via the AMPK-mTOR signaling pathway.

Cyclophosphamide-induced testosterone deficiency (CPTD) during the treatment of cancers and autoimmune disorders severely influences the quality of life of patients. Currently, several guidelines recommend patients suffering from CPTD receive testosterone replacement therapy (TRT). However, TRT has many disadvantages underscoring the requirement for alternative, nontoxic treatment strategies.
